CRIMPING OR CORRUGATING MACHINE.

Specification of Letters Patent.

' Patented June 19, 1917.

Suifolk, respectively,

in the State of'Massachusetts, have invented an Improvement in Crimping which the or Corrugating Machines, of followlng description, 1n connection with the accompanymg drawings, is a specification, like characters on the drawings representing like parts. Y

This invention relates to a crimping or corrugating machine and is herein shown as embodied in a machine for crimping or corrugating the lip of an insole for boots and shoes, larly ,appli The invention for which purpose itis particucable.

has for its object to pro-- vide a superior machine for the purpose specified, and one WlllCll is simple 1n construction, easy to operate and w1th whlch the insoles lips of the may be provided with crimped same or unlform helght.

1 The invention further has for its object to provide a machine in which one of the be utilized for turning the lip into position to be crimped.

Provision may and preferably will be made for pressing portion of the lip toward the body the insole after the lip has been acted uponby the crimping tools, as will be described.

- These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a plan of a machine embodying this invention.

Figs. 9 and 10, details. of the oscillating crimping tool, and

Fig. 11, a detail of the device for insuring uniformity in the height of the lip.

Referring to the drawings and particularly to Figs. 6 and 7, a represents an insole for use in welted boots and shoes, and preferably made of substantiall non-stretchable material, such as hard fiber. The machine which forms the subject of the present invention is designed to turn up a lip Z) on the insole, and provide said lip with transverse crimps or corrugations 0, shown in Fig. 8.

To this end, the machine is provided with tools for crimping or corrugating the lip b transversely, one of said tools-being movable toward and from the other and having an oscillatory movement, whereby it acts to turn an uncrimped portion of the lip into position to be crimped, and also forms a crimp or corrugation in a portion of the lip which had been previously turned up into proper position to be crimped.

In the present instance, the oscillating tool is shown as a substantially wide finger 10 on the end of an arm 12, attached to or forming part of a pivot pin or shaft 13, which is mounted to turn in a bearing hub 14. The finger 10 is provided, as shown, with a substantially flat face having in it a plurality of substantially parallel cavities 15, 16, and the arm 12 is shown as substantially triangular in cross-section with the apex of the triangle at the lower edge of said arm.

The crimping tool 10, 12, is oscillated toward and from a cooperating tool, which latter may be made as herein shown of two rods 18, 19, (see Figs. 3, 4- and 8), which in the present instance are connected at their upper ends by a cross bar 20 and are mounted to slide in grooves in a carrier or block 21, secured to a head 22 attached to a lever 23, mounted on a pivot pin or shaft 24 (see Fig. 5), which is journaled in hubs 26 attached to the framework of the machine.

,The lever 23 is provided with a laterally extended arm 27 to which the bearing hub 14 for the oscillating tool 10, '12-,is secured,

the lever 29 atone end,'and a like conn'ec tion at the other end witha projection 31 on the arm 12 of the oscillating tool.

The lever 29 is mounted to turn on a pivot pin 32 '(see Fig. 5) of the lever 23, so that the lever 29' is capable of beingm'oved independently of the lever 23 to rock or"oscill'ate the tool 10, 12, and effect a transverse crimp or corrugation in the lip Z), and is also capable of moving wit-hthe lever -23 so=as'to feed the insole by means ofthe crimping tools. The movement of the lever29, 'which'ef fec'ts the oscillation of the crimping tool 10,- 12, is accomplished as herein shown by means of a path cam351n one side er face ofa wheel or disk-'36 mounted on a shaft 37, the path cam'35 having eXtendedinto-it a roller 38 carried'b'y the lever-29.

The movement of the levers 23, 29, which effe'cts'the feedof the insole, is accomplished by cams40, 41, on opposite facesof the disk 36 near-the circumference of the same, whichengagerollers-42, 43 (see Figs. 1 and 2)' carried-by'thelever 23 and engaging said cams; 1

The-path cam 35 is suitably shaped and timed to-rockthe crimping tool 10,12 for-- ward or toward the cooperating crimping tools 18, "1-9, from substantially the position shown inFig; 6 into that shown in'Figq 'Z, so as to form a crimp, marked 43 inFig. 8, in ian unc-rimp-ed porti'on'of the lip .71, and to retain the crimp c, which was'previously formed, I from being distorted while I the crimp 43 isbeing formed.

The oscillating 'tool 10, 12, may and prefera-bly willihavecocperating with it a backing-member,shown'asan arm 45, which attached to the lever 23, and is provided as shown-with a curved-' 'portion 46' (see Fig.

6), which'confoi'ms to the curvatureof the upper surface of the arm 12 of the -oscillat-- ing rimping toola It will" thusbe seen that the oscillating crimpingtool '10,l2 in the machineherein shown, on its forward 'movement from the positionshown-in Fig. 6 into thatshown in F 1g. 7, serves a three-fold purpose, to wit: it serves to prevent distortionof a previously formed crimpc bythe cooperation ofthe cavity 16 andthe rod 19, and forms a new crimp-43-by' the'cooperation of the cavity 1'5 and rod 18, and also servesto turn over an uncrimped portion of the lip of the 7 insole into an'inclined position readyto-be crimped." The oscillating crimpingtool cocarried by the hub 33 operates with thetools'lS, 19 to feed the indirection to the feeding movement to bring the crimping tools into their starting position, in which theyar'e in'proper position to'--en ga-ge the last-formed crimp-43 and to form a new crimp in the turned-over portion of the lip.

It is desirable that the -lip'b in'the completed insole should be of uniform or substantially uniform height throughout its length, and-provisioiris made for effecting this result. To this end, a gage or device is provided-with which the free edge of the uncrimped portionof the lip is designed to be engaged, when the latter is being turned over-by the oscillating tool.

In-the present instance, we have shown oneconstruction "of gage for this purpose, which consists of a finger (seeFig. 11), which is attached to or forms part of a stationary plate or bar '52, secured to the framework of the machine, and having a substan'tiallyflat under surface and an inclined upper surface 53, which forms with-the flat undersurface a substantially thin edge 54, which'is designed toenter between the lip'b in its fiat condition and the 50 on a block'5l' feather'55 of the insole, and'initially open up th-e lip when the insole is placed in the machine. The inclined upper surface 53 serves as a wedge to turn up the lip Z) from its substantially fiat position parallel with the feather 55 to which the lip is turned up is limited by the finger 50 with'which the edge of the lip b engages, and when the edge of the lip en gages the underside of the finger the said edge is turned over slightly, prevented from being turned up any further, and is thus made of uniform or substantially uniform height throughout its length, which of the insole, and the extent and the lip is 57 to grip the the crimped lip a pressure which serves to retain the crimped portion of the lip in its turned over position while another portion of the lip is being crimped, which isespecially useful while the lip at the toe-portion of the insole is being crimped, and especially the narrow toe portion of pointed shoes. To this end, we employ a presser finger 60 on an arm 61 attached to the framework of the machine, said presse'r finger being extended over the table and in proximity to the crimping tools when the latter are at the end of their feeding movement, so that the crimped-portion of the lip is caused to pass under the presser finger 60, which holds the crimped portion down with sufficient pressure to resist and counteract tendency of the crimped lip to straighten up especially at the toe portion, while adjacent portions of the lip are being crimped.

The features above described, to wit, the oscillating crimping tool, the gage for obtaining a crimped lip of-uniform height, and the presser for holding down and retaining the crimped lip in the position in which it leaves the crimping tools, are embodied in a machine in which the operative parts are in the main substantially the same as shown and described in another application Serial Number'44392 filed by us on the ninth day of August, 1915, but by reason of the use of the oscillating tool, the operative parts of the machine are materially diminished and simplified.

Referring to Figs. 1 to 4 inclusive, the shaft 37 'on which the cam disk 36 is mounted, is driven from a main shaft 62 by a friction drive, consisting of a driving wheel 63, mounted on the main shaft to rotate therewith and to slide thereon, and a driven member or disk 64 fast on the cam-shaft 37.

The main shaft 62' is j ournaled in a rocking frame 65, which is acted upon by a spring 166 to normally keep the driving member 63 out of' engagement with the driven .member or disk 64, but which is compressed to permit the driving member 63 to be engaged with the driven member 64, by moving a'projection 165 on a collar 66 from a recess 67 in an annular boss 68 on an arm 69 of the rocking frame, and bringing the said projection into contact with the face of said boss. When the collar 66 is turned so as to engage the projection 165 with the face of the boss 68, a collar or ring 70 is moved on the rod 71 so as to remcvc the end wall of a slot 72 in said collar, away from a pin 73 on the said rod, thereby enabling a spring 74 on the rod 71 to overcome the spring 166 and rock the frame 65 so as to engage the driving member 63 with the driven member 64. By turning the handle 66 so that the projection 165 enters the cavity 67 as shown in Fig. 2,

the end wall of the slot 72 engages the pin 73, and the spring 166 becomes active and moves the driving member 63 out of engagement with the driven member 64.

The speed of the cam shaft 37 may be varied by moving the driving member 63 on the main shaft toward and from the center of the disk 64, which may beeffected by a bell crank lever 76, connected by'a link 77 to a'treadle (not shown).

The table or work-support 58 and its movable section or gripping jaw 57 are operated substantially as shown and described in detail in the application referred to, and as this construction is not herein claimed, it is deemed unnecessary to describe the same in detail, but merely to state that the movable section 57 of the work-support is held up in its elevated or gripping position by a lever 80, which is acted upon by a path cam, not shown, in the face of the disk 36 opposed to the path cam 35. The lever 80 carries a screw 81, which engages a wedgeshaped bar 82, pivotally mounted in the forked arms 83 of a lever 84, which is mounted on the pivot pin 85 supported by the frame work. The wedge bar 82 supports the spindle 86 of themovable jaw 57, and the said jaw is lowered by a spring 87, when the latter is permitted so to do by the cam which acts on the lever 80.

The table or work-support 58 is lowered at the will of the operator by a treadle, not shown, but which is connected by a link 88 with an arm 89 on the hub of the lever 84,

carries a second wedge-shaped bar 90, upon which rests the spindle 91 of the table 58, which spindle is lowered by a spring 92, when'the wedge-shaped bar 90 is moved so as to bring its reduced portion 93 beneath the spindle 91, which is effected by the operator depressing the treadle with. which the lever 84 is connected. 1 I

The table 58 is lowered to permit the operator to properly position the insole in the machine.

The crimping tools 18, 19, may be rendered inoperative to crimp the lip, at the will of the operator without interfering with the feed of the insole by the crimping tools, by means of a lever provided with a slotted hollow boss 101, into which the cross bar or head 20 of the crimping tools 18, 19, is extended.

The lever 100 is connected with a treadle, not shown, by a link 103, and when the said treadle is depressed, the lever 100 is turned so as to move the crimping tools 18, 19, lengthwise, so as to withdraw them from their operative position with relation to the crimping tool 10, 12, shown in Fig. 6, into their inoperative position shown in Fig. 7, with the result, that the oscillating tool 10, 12 on its forward movement presses the lip which b against the substantially flat lower end of the carrier 21 in which the tools 18, 19, slide, thereby enabling the crimpingwtools to feed the insole by the portion of the lip -which it is desired not to crimp, as, for in- 9 and 10), which engages the uncrimped portion of the lip and avoids any danger of tearing the lip when the oscillating crimp? ing toolfolds or turns over the uncrimped portion into crimping position. x

The oscillating crimping-tool is herein.

shown as embodied in a machineinwhich the crimping-tools effect the feed 0f theinsole, but it is not desired to limit the invention in this respect.
